Rails - Sep 2010 - invalid argument for file creating

hi
  I use song_title to creat a file named by song_title.I have many song
titles to create many files.but unfortunately,some of song titles
contain special characters,such as [ ,which leads the following error:
#####
Errno::EINVAL in Lyric spiderController#scrap_one_category
Invalid argument - e:/rails/lyric/public/song/e/Energy/
[ar:Energy.lrc
#####
I use the following codes to create and write to files:
#####
 File.open(singer_dir+"/"+UTF8_TO_GBK.iconv(song_title)+".lrc",''w'')do
|f|

   f.write(lyric_initial_data)

 end
#####

It is impossible to drop those special characters individually,and they
are valid file names on my windows system when i manually create the
file using them.
I have used the CGI escape methods,but the resulted filename was not
what i want.

how to keep those characters for file name,and prevent the error
happens?

I don''t have any direct experience with this, but perhaps you could
begin isolating the problem by trying to directly pass a hard-coded
string as in
     File.open("this_is_the_title.lrc","w"),
sidestepping the filename creation process.
